TAPPET FOR SPRAYERS.

Application filed. June 29, 1912. Serial No. 706,687.

To all whom it may concern:

Be it known that I, CHARLES ABNER CL'AY- TON, a citizen of the UnitedStates, residing at Sweetwater, in the county of Nolan and State ofTexas, have invented certain new and useful Improvements in Tappets forSprayers, of which the following is a specification.

My invention relates to Sprayers, and particularly to a spraying devicewhich may be attached to a cultivator or other wheeled implement.Sprayers of this class commonly comprise a tank for the storage of aliquid desired to be sprayed onto plants, a pump, and a series of spraynozzles connected with the tank.

The object of my invention is to provide a device of this characterwhich is easily and quickly applied to a cultivator frame, and which isoperated by the movement of the cultivator wheels.

An important object is the provision of novel means for operating thepump.

A further object is to provide means for regulating the amount of liquidsupplied to the nozzles, and also the pressure of the air.

Another object is to provide a device of this character which will besimple and efficient in operation, cheap to manufacture, and durable inservice.

With these and other objects and advantages in view, my inventionconsists in the novel arrangement and combination of parts ashereinafter described and claimed.

Referring to the drawings wherein is illustrated the preferredembodiment of my invention, Figure 1 is a side elevation of my deviceapplied to a cultivator, one wheel being removed, Fig. 2 is a detailview of the tappet attached to one of the spokes.

Referring more particularly to the drawings, A represents a cultivatorframe supported upon wheels B.

My device comprises a base plate 1 secured upon the frame A, preferablyby bolts 2. The forward end of the plate 1 is provided with a lateralextension 3 upon which is mounted a storage tank or reservoir 4. I haveshown the tank as being of cylindrical form, but do not limit myself inthis particular.

A pipe 5 connects the tank 4 with a pump casing 6 mounted upon the baseplate 1. This pump is of the common force-pump type, and needs nodetailed description. The piston rod 7 is provided with a de-Specification of Letters Patent.

pendingportion S, fora purpose to be described, and an eye 9 forengagement with one end of a retractile coil spring 10 which issecuredto a bracket 11 upon the plate 1.

The depending portion 8 of the piston 7 extends through a slot 12 in theplate 1, and is disposed in the path of travel of tappet levers 13secured to one of the wheels B. These tappets comprise clamping plates14 and 15 pivoted to each other as at 16, and adapted to receive thespoke 17 in the wheel B. A bolt 18 passes through the plates 14 and 15and clamps the device securely upon the spoke. Connected with the plate14, or preferably formed integrally therewith, is an extending member19, upon which is journaled a roller 20, held in place by a nut 21 uponthe member 19.

It will be seen that as the wheel revolves, the tappets 13 willsuccessively engage the depending portion 8, and operate the piston inone direction. When the wheel has revolved sufi'iciently to release theportion 8, the piston is moved in the opposite direction by the spring10. It will also be seen that by moving the tappets along the spoketoward the hub of the wheel the length of the stroke of the pump may beshortened, and vice versa.

Communicating with the tank 4 is a pipe 22 connected with a pressuregage 23. Another pipe 24 communicates with the lower part of the tankand is connected with laterally extending pipes 25, provided withbranches 26 terminating in spray nozzles 27. The pipe 24 is providedwith a valve 28 for regulating the amount of liquid supplied to thenozzles. Pipes 22 and 24 are connected by a pipe 29 provided with avalve 30. By regulating the valve 28 the amount of liquid supplied tothe sprayer nozzles may be varied as desired. The amount of air passingout with the liquid to the sprayers is varied also by means of the valve30. It will be observed that by opening the valve 30 an atomizing effectis produced. The tank 4 is providedwith an opening for filling closed bya screw cap 31. Q

The numeral 32 designates a safety valve of any well known or preferredtype.

I have shown my device as being oper ated by three tappets, though I donot wish to limit myself in this particular, for I may provide as manyspokes as desired with tappets in order to increase the speed of the pmp.

ing portion hinged at one end upon said body portion, and a bolt forconnecting the other end of said clamping portion with said bodyportion.

In testimony whereof I hereto aflix my signature in the presence of twoWitnesses.

It will be understood that various changes in the form, construction andarrangement of parts may be resorted to Without departing from thespirit of my invention or limiting the scope of the subjoined claim.

Having thus described my invention What I claim is:

A tappet adapted to be clamped upon. one of the Wheels of a sprayingdevice comprising a body portion, a projecting spindle, a rollerjournaled on said spindle, a clamp- Copies of this patent may beobtained for five cents each, by addressing the Commissioner of Patents,Washington, D, G.
